[Closed] Frame and Fork upgrade questions

Currently I have a 4year old Trek Superfly carbon hardtail. The fork has seen better days. Which leads me to some ideas. Firstly, the current fork is a 51mm offset, looking at the recent crop of RS forks they seem to be generally in the 44mm area. I am aware that new forks are boost and the current is not, but such is life.

Am I going to notice 7mm? Really???

Then the other thought, maybe a new frame, does anyone have real world experience of the Procaliber v Superfly? Is the back end actually more comfortable?
