What I ended up doing and what I found out.
I got a 45X20 12 mil cover and put in on a reel, bought a 2nd cover big enough to cut in half to cover the "L" part of the pool, this is not on the reel and I get 2 covers for less than what it would cost if I bought something to exact dimensions.
I got a Commercial grade 20 foot Reel (Elite Reel Systems Pro 2000) from a co-worker who didn't want his anymore. Think they retail for about $400 and it seem like a quality piece of equipment. **Note prices when you buy, I noticed some reels did not include castors which accounted for the price difference at some sites.
In speaking with other peopel and from what I can see from very limited use you don't need weights or drains on the solar covers. Think these are additional money makers for the pool co's.
One person can put the cover on and off with a reel, 2 is easier and in a pool this wide with an "L" you need to pull it on the pool on one side and fish the cover over with a pool brush on a pole so you can get it straight int he pool.
I will post again end of season to remark how it worked out and how much I actually used it.
