Markman drifter is a lovely rod, along with a cortland sylk line (or a DT when wind is light) it's a great dry fly and nymphing rod for the lough. action is soft enough to protect light tippets.
There are very few 10ft 5# with a FW handle which I prefer in the boat.
However the £100 price hike that this rod received the start of the year was probably too much to justify if I was buying again. Although obviously give Grommit a ring for a price!
I had the streamflex but always felt it lacked any back bone but i am used to much faster rods and it always felt a bit alien to me and took too much adjustment to enjoy. The new XF2 looks interesting and I know Trout hunter and Dooras won one each recently, so they may be worth contacting to see how they got on with it on the lough.
If I had the choice again I think I'd be tempted with a custom build 10ft #5 z-axis with an full wells handle from the US.
Just remembered that Grangers have all z-axis on sale currently, had a few good deals there recently. they have a 10ft #5 with £200 off -
