[Closed] Nicolai helius help me chose !

I am 40 this year and am treating myself I think to a nicolai. Had a look and struggling to decide between the helius ac or helius tr with 29 inch wheels. Ride mainly in the peak with trips to Scotland, lakes the odd alps trip, generally full days in the saddle and enjoy the technical descents. I tested a tallboy lt and really liked it but unsure which will suit me best. The tr is slacker than the tallboy with shorter chain stays so looks like it might fit the bill or do I go for the more aggressive ac. Anyone got one, ridden one etc, any advise appreciated.
