Well its all solved!!
No funtana 90s in the UK til next week so there was me feeling all depressed (money burning a big hole in the pocket) and out of the blue an email from EF saying they have a UK distributor! So I've now ordered an EF 68" Yak for the YS110!!
I know this is the right way to go, but I may buy an F90 just as a backup kit!!
And cumn thru, I know exactly what you mean about the mess, its a nightmare! It's my intention to go petrol next year either wildhare or comp arf if funds allow.
