IME bike fit isn't rocket science and you shouldn't be afraid of experimenting yourself. Just make one adjustment at a time and make a note of the starting position so you can undo the change if it doesn't improve things. Just movie g the saddle forward a bit might make a world of difference.
I am going to move it and tip is slightly downwards, originally when they did the fit they didn't have the saddle i had previously, i bought that a couple of weeks after as they had it in stock and it's a saddle i also have on my old bike, it's comfie as you like and works well.
just been thinking about the various pointers people have given me in various posts, and i think it could relate to the saddle now being parallel where as the original was slightly forward and down.
only reason i am a tad wary with this bike as it's so different to anything i ride normally, honestly flat bars are simple haha

much appreciate all the tips though it's given me ideas to solve the problem.
