IMO, ya can't go wrong pulling the trigger on either the (tapered) machined premium mandrels from HMH*, or the new NorVise tube fly attachment. If you really want to go 'whole hog' (or if Santa thinks you've been a good boy) the HMH Tube Fly Vise would look nice under the tree.
I use all three.
Then again, I've been a very good boy this year.
*The only difference between the HMH 'standard' tube fly tool and the 'premium' tool is the tapered mandrels.
