Thanks for your replies guys, I just needed a little persuasion.
I think the 661 is more than I need. I don’t fancy wielding a 30 inch bar and I’d prefer to avoid the additional weight.
So for me the choice is either the 462 or the 500i. Pricewise there is little difference, the 462 with 25 inch rollomatic E bar is £934 and the 500i with 25 inch light bar is £1,055. I’m not worried about the new technology, I have other Stihl equipment and I trust the brand.
I guess I’ll go with the 500i, I’m sure it will handle the bigger stuff for me and I doubt I’ll be disappointed.
Cheers
