My issue with ME is partly that I just don't know it as well and thus was hesitant to head down Exterminator and Lower FIS cuz I didn't want to commit to something that might be long and shitty. I wish I did both. I'd like to explore ME more when there's fresh snow.
For Exterminator, you can always cut in via the crossover that comes from Elbow across Bravo and over to Ext. That cuts off the top 1/3 or so and can be a good option if you want to test out a shorter part of it (and you avoid the slightly steeper part at the very top with the biggest bumps).
Lower FIS...generally speaking this trail has some of the best snow on the mountain and the bumps are almost always on the smaller/more manageable side. I can link numerous turns pretty well here (and I get the impression we're likely both somewhat similar abilities). The only thing that sucks about Lower FIS (and also the reason it sees so little traffic) is the runout. The runout is a workout as a decent portion is slightly uphill.
