Thanks for some great help guys. Based on your advice I bought some 2315 Plats today and shot a 570 Portsmouth with them this evening. I too thought that the balance of the Tribute was very weight forward (certainly compared to the recurve) but not having shot any other compounds before I thought this was a common thing with compounds, I'll have a play around with weights and try for a better balance. Although the bow is 50lb-60lb I was surprised to find that on a shop's scales it measured 46lb (Pete had wound it down as far as it would go before I bought it), we upped the weight to 51lb and thats how I shot it this evening. Dont think I'll be going any higher for a while although I seem to remember reading somewhere that Bowtechs perform better nearer their max draw weight.
