Crank arm always coming loose.

How do! First Post so please be gentle!

Firstly, my bike..

I have a 2010 Scott Aspect 45, which I absolutely love.. but has a big niggle which bugs the absolute hell out of me!

Considering the rest of the 'kit' fitted as standard is of pretty decent spec (well, in my opinion anyway!), the bottom bracket/ crank arms are a bit of a let down.

I don't know if it's just me being quite heavy (16 stone, 6'3"), but the last two bikes that have used a square taper / UN (26) cartridge type bottom bracket (my Scott and my previous Giant) have both had the left crank arm come loose on a regular basis and bearings become far from smooth in a short space of time. I don't particularly abuse my bike and use it primarily for commuting with a little play in the rough stuff when I can.

Can I change my bottom bracket set up for something different to square taper, how difficult would this be and what would I need to change? (I assume just the crank arms to one that are compatible with the BB?
Suggestions of what to do/ go for would be greatly appreciated :)
