Yeah, I know the standard oil is 7.5w, didn't realise how much of a difference the 10w would make. I'm 87kg, so though the heaver oil wouldn't be too much to handle.
Got a dhb merino base layer top from wiggle. Tried it out on the turbo tonight and it reaally does wick away the sweat, will get a good test at dunkers, pretty good value at £22 in the sale.
