I did kettlebell triceps extensions my last arm day, it was a different type of movement with the hands positioned the way they were, I hurt for a couple days after, pretty good feeling... not saying kettlebells are anything special ( as was said in the kettlebell thread a little while back ) but it was a good change from the close grips, dips, pushdowns variations, went high rep drop sets with about 60 sec breaks between cluster sets- did 3 sets of 3 "drops" for 15 -20 reps each time, so had 9 total sets of high reps in about 3-4 mins, long head of the tricep was smoked
If you need to change your tricep workout up,give it a try, you will be pleasantly surprised, finished it off with 3 x20 rope pushdowns, 45 sec breaks between sets
