It's a personal thing Brian..... get over a #7wt in a Switch rod and my mind tells me I'd be as well using a short #6wt double hander instead
Which is actually what I do use..... currently I do not own a switch rod
The original Helios in a #7wt would be my choice - no question - of the rods mentioned in your post. It's the closest I have come to parting with cash to buy into the switch rod idea, I think it's a belting rod, perhaps only bettered by the Mackenzie switch rods
The Access is a fine rod, but the original Helios is just that leap better in my opinion, it's the premier rod.
If you can test them all out, that would be very good indeed.
