Well, I certainly don't have anything to say that would compare with the amount of knowledge and experience that has already graced this thread. Under its influence, I will try SS tanks (that just looks weird - but I am a WWII buff...) However, what I think I can add is a bit of a relative begineers perspective, perhaps those starting out will be able to relate - and better yet, avoid my mistakes.
Like many of you, my first steps in photography were based on someone else's knowledge and experience - in my case a very close friend. For lack of knowing any different, I went out and bought what he used - when you first start, out WOW! it can get pretty confusing sifting through all the opinions and preferences!(Just look at this thread!).
So, I went out and got a Patterson tank, used with one of their adjustible reels. I promptlyignored all the sage advice of practicing in light, and went further by rushing into the darkroom (pantry type closet in the basement

). It was winter. My wife went out for a smoke - and I told her that she can't come back in until I am done. She asked how long it would take. I thought - well, my friend got this done in about 5 minutes - how can I take any longer than, oh... 15minutes? Given this, she went outside and agreed not to come back until I get her - as any light, anywhere in the house - would get into my makeshift facility.
I killed the lights.
I felt my way around (I did have the foresight to set things up in logical, easy to access hands reach and order). It was a roll of 120 - so I unrolled the backing and did a reasonable impersonation of someone who knows what he's doing of separating it from the film. So far so good.
Here come the tips on Patterson tanks and reels:
The reels CAN be assembled wrong - when this happens, the loading ramps do not line up on both sides of the film... The previous owner did this. I didn't check it. I had to figure it out in total darkness, while holding on to a roll of film. It took a long time. My feet were freezing. The awareness of my wife seething with hatred outside the door was weighing on me like a rock

. All the coffee I drank that day... well, it wanted to leave - now, if possible.... And I was FIXING my TOTALLY UNFAMILIAR reel in total DARKNESS while expecting my wife to at least kill me, with numb feet, sweaty palms (mind racing with images of the sweat ruining my film - making more sweat happen...) and Scotty from Star Trek somehow talking (in my head...) about my bladder: "She cannot hold it any loner, captain!"
And that was before I loaded the film...
All told,40+ minutes later I was finally done and ready for soup...
Which leads me to the only other tips I think anyone who is not as silly as me will need:
The reels need to be cleaned THOROUGHLY and DRIED THOROUGHLY. Water (and whatever chemical residue) gathers in the grooves and takes forever to dry - this will show on the edges of your film if not taken care of. I always disassemble the reels into halfs for cleaning and drying, and inspect them thoroughly before use.
The reels, I find, are very, very easy to load - have not used anything else, mainly for lack of a percieved need. One tip - keep your thumbs over the loading ramps - that way you will know (feel) if the film skips out on you as soon as it does (it also seems to decrease the chance of that happening).
One thing - if you get unusual effort required to load - stop, pull some film back - DO NOT force it. It usually fixes itself with a little wiggling and cursing
The tanks all leak - all the Patterson tanks I have ever used or seen used - leak. I use the little twisty-wand device to agitate, or swirl the solution the way you would ice in the bottom of your glass. Both seem to give me no problems at all. Inverting, as performed by me, makes a mess with these, so I gave up and have not seen results indicate I should revisit.
The moral of the story?
A roll of ruined film cannot do a fraction of the damage a really, really ornary wife can do - and hurts less than a bursting bladder. I cought a cold from the concrete basement floor.
I have some nice pictures. I tell myself it was worth it
The end.
