Right I'm still reading it but I found an article RE fast and slow twitch muscles fibres that might be of interest:

And another one:

It is generally accepted that muscle fiber types can be broken down into two main types: slow twitch (Type I) muscle fibers and fast twitch (Type II) muscle fibers. Fast twitch fibers can be further categorized into Type IIa and Type IIb fibers.

Bsically i think from these articles the evidence is inconclusive although granted I might want to keep looking for more up to date info.

I'm wondering how much mentality comes into it also.

I feel most confident with a strong endurance base and I think longer workouts tend to be a good outlet. I generally only need one real endurance and perhaps one semi-endurance workout per week to see improvement. I don't see it including these sessions as being at the cost of other workouts neccessarily since I doubt I'd make gains from having more than 2 max 3 speed sessions a week?
