hi Steven,
as Eddie mentioned me, i'll chip in.
I've three 10 foot 4 weights, all from Orvis, and all great. My go to rods for rivers and lochs. I like the extra reach of the 10 footer, and fish dries mainly, with nymphing/spiders if need be. The
I do love the Helios one; the Access one is great too, just not quite as lovely in terms of looks.
So, yes, i'd 100% recommend a 10 footer 4wt, but i've only really tried my own ones, so don't have anything to add re other brands.
If I was going to buy a new one at the moment, I'd probably cast at eye at a Mackenzie NX1 or the Orvis Recon
cheers
