Yes I'm sure there will be lots of input.
For myself, I didn't want to do the whole conversion either, and like you my chain stretched a lot. I, like you used the adjusters (not to keep the chain tight but to keep the proper slack that is needed, only reduce the amount that's stretched. Check the manual.) to pick up the amount that stretched during riding.
I got a 428/ D.I.D. / NON- O-ring, cheap (about $40)from my local bike shop, and they cut it to size for free. It stretched too but not near like the stock chain, I only adjusted it twice I think. You'd have to lube the chain more than the O-ring type. But it is cheaper.
Hope this helps, Jaime. I type slow.
