Finally getting around to having all the parts installed on my 15 and last couple items are remaining on my list to purchase. I was holding out to see if Riva was going to release a SS grate, but wanted to see if anyone has had success with the TBM unit (I know most peoples Ski's have been in storage since it was released, but still a few of us that have riding weather). Rather order it now if it results have been positive over a stuffed stock grate just to save on shipping costs if I order it later, would still run stock and get logs and then switch to get my own results to compare, just don't want to spend the coin if its not really worth it as the stock grate is pretty decent.
