Definitely, you like to do things right the first time too, sorry if that sounded a little pointed, it's not what I intended....
I bought the neoprene kit you see in the catalog from the local hobie shop. With most hobie branded or sourced stuff you know it will be quality and it will all fit and work together correctly with rare exception, and this kit is no different even though it is just rubber matting, 3M contact cement and a $1 brush. I could justify the cost of the other kits even further where the neoprene is cut out in strategic places to fit around posts and grommets, etc.
I'm definitely a fan of cooking my own recipes and finding my own solutions. In this case I just bought the kit and did it. Probably could have saved some moolah sourcing elsewhere but I'm finally getting it through my thick skull that at this point in my life (43 with 8 y.o. twin girls) I don't have to re-invent the wheel EVERY time

....So, I don't know where else to send you, I can only tell you what I did.
One nice thing I can tell you about the kit is that the leftovers are just long enough to install on the outboard aft topsides for trap footing when down winding when it really gets blowing. Flip to page 9 of the current catalog and note the "Race strips" kit description item number 16707, and also check out the "Non-skid" item number 16713 also on p. 9, both of which the leftovers make unnecessary - bonus! The pic on p. 26, which looks like a 17 Sport to me but what do I know, shows similar strips installed aft of the tramp all nicely contoured, but serve the exact same purpose.
I bought the aftermarket standing (and running) rigging on eBay and so far so good. In the future I'll go to the local shop (b/c I believe in spending locally), or Surf City, or Murray's. Each of which I know offer competitive pricing ad will stand behind their sales and all offer great support. One thing to note, on the running rigging I got from eBay, the main halyard was ~6" too short, which was just enough to make it unusable. I told the seller and while they were certain they cut them accurately they asked me to re-measure (I did and sent photos) and once convinced they sent a new one.
I'm in the same boat you are. I read the catalogs, Hobie's and Murray's, like textbooks and read this forum until my eyes bleed, but it's not like I have deep knowledge b/c I don't have a lot of experience yet, just common sense and a willingness to take some chances and learn. In the end, the bulk of my learning has been from this forum.
