I am 6'4" tall. I weigh about 200-210lbs clothed. My height is fairly evenly distributed between legs and torso. My arms are rather long, though.
Please help me start developing a shopping list for a decent glider that I can enjoy owning and flying without cramps or impeded control movements. This would be my first foray into ownership, but I expect to own multiple in the future.

Factors to consider:
1. Prefer 2-place to single-seat, but I'm open to both.
2. If 2-place, must be FAA type-certified with standard airworthiness certificate. No experimentals. I want to be able to give commercial rides, instruction, and CAP cadet o-rides. Solo ships can be experimental, but not amateur-built.
3. Will consider self-launchers, sustainers, and motorgliders, but not looking to get into that price range.
4. Will consider antiques & open cockpits, if they have a provenance.
5. Not concerned with competition.
6. Acro would be a plus.
7. Will consider something life-limited (e.g., Lark) if I can get it super-cheap to use as a disposable platform for a couple hundred hours to better identify what I really want from a glider.
8. Priced under $30k, $10-15k is better.

My experience:
Highly active airplane pilot, IFR, 1000+ hours. Low-time glider pilot (100 hrs).

Here's what I have flown:
L-23: Fits okay, not very charming to own.
ASK-21: Tight, but doable
G103: Tighter than the ASK-21, prefer to avoid
Bergfalke: Antique wooden open-cockpit novelty; not a candidate.

I'll be trying out a SGS 1-23 and an LS-1f this weekend. There are several KA-6 models for sale all over right now (did they just get hit with an AD or something?), so some targeted opinions on these 3 would be timely.

Cheers

We have two guys in our club, one is 6'6" (Bill) and the other 6'7" (Chip). Both guys will ONLY give rides in our G103. Bill is an Ex Air Force Col., who had a similar problem as you. He found an LS4 that was the "most" comfortable for him. He took the Seat Back out and flies with a parachute against the bulkhead and has had numerous 4+ hr flights. You also might consider an LS3a without a seat back, if you would like flaps? I hope this helps? Happy Searching!
