Any slim line kit can be made into a "long wood style"
The upper pen in this picture is made from a basic slim line but it would be just as easy to use a TN kit or any other MFGRS upgrade plated slimline.
I don't care for rubber "comfort grips" and make my own accents.
Measure the "long woods" you have(allow for the center band) and if you dont mind not having the rubber gizmo on the lower end you can save some money abd still make a pen with a similar design.
The lower pen in the picture is a PKMON PAR.Parker style long wood.They are a little trickier but not that difficult.
