I have both of the Lee 124 and 125gr, 6 cavity molds as well as a MP version which is very similar but allows for HP's.
I will be pouring up a batch of the Lee's today as a matter of fact and will probably be coating them with some HF Red sometime later this weekend.
I like them both but the TL version seems to hold the powder a bit better and usually only needs one coat where with the slick sides on the other one I usually do two coats. Might not be necessary, but getting 150+ at a time in the little oven, it doesn't take a lot more time to add that second coat.
