right.........my west runs on Bekra, got kinda the same stuff in it, no caster all klots, but its red, i think weston say this for advertising, no one in our club useses prosynth, i had a gallon once but i used that, then i switched to bekra cos Dr.J gets it cheaper.

My west runs at 13,000rpm, i tunend it for ages to get the best of it, the tach was a real good quality one, i'll try and take a pic of it within the next year the only 2 downsides to the west are that the props are expensive that they need and the bit on the needle which keeps it in place is very soft metal and min snaped.
