^^^^^ Indeed, I was trying to be charitable. That's basically the real question. At 69.69 inches with flip flops (giggity!) I've sat in a 3; I have seen no evidence it is any
more accomodating than a II for a 6'3" occupant, especially if the ergonomics of the individual make them long torso vs long legged. I'm open to stand corrected as I haven't sat in a 2, only a 1, which is why I can say the 3 is more accomodating than a 1.
I do know for a fact he would
not "fit" with any semblance of functional definition (eg for traveling/commuting) in either the G1 or Lanc235.
I stipulate the fact G-IIIs are in the vicinity of pricing as most clown-priced 4 seat spam cans of much much lower performance in present circumstances. So that one pencils out. But if the choice here is against an RV14/A? Then yeah forget it, I'm unironically suggesting eating the opportunity cost of fac-built ownership. RV14 pricing is the biggest phyrric victory I've seen since BasicMed let the walking MI-crowd roam free (I keed I keed). And this is coming from someone who rage quit the PA-28 over fac-built AD nonsense mind you.
Seriously, speed is overrated for the ranges being contemplated. Eating 400NM (the average between the stated legs) at 130-145 block vs 200-220 ain't gonna change your life. I do M.9 for an hour at a time and someone else has to fly my underwear; I'm telling you the T-6II smokes us on the overall balance for a XC cruiser at half the speed. 300nm is too short a leg for these speed deltas to matter, it's all hat no cattle.
As I said, there's penalties in this hobby for being in the 99th percentile of adult height. Can't win 'em all. Go date 6 foot women with thighs and rear bumper twice the diameter of a short but smiling man's smothered face

and take the height lottery W you privileged whiner.
