Had exactly the same problem. 6ft5″ here. Could and would have saved myself over a grand if that pitch offer had been around 4 months ago.
My personal view on bikes and “not getting on with them”, is that as humans, we are pretty adaptable.
You’ll get to like/get on with whatever you end up with. Just because it doesn’t “feel right” the first time, or even tenth time you ride it, you will adapt to make the most of it. Your style will adapt, and then when you try something else that once felt great, but now doesn’t, that would be why.
Just my thought anyway. Might be pure ignorance based on the fact that i’ve only ever ridden two full suss bikes.
