Do you think it worth switching the tower over? The old b6.4 shocks used longer eyelets so I think they will be similar in overall length.
I'd say the longer tower + longer shock bodies is worth using if you have the parts but not worth hunting out the parts specifically.
Overall shock length is one thing but the main performance differences come from managing the balance of up-travel vs. down-travel. With the longer shock bodies + taller tower we could effectively run the piston less in to it's total travel for a given ride height which makes the damping more consistent in the normal range of motion. It is very subtle and only the very best drivers can exploit the difference in feel.
