Rath has them now. From what I understand AC has standard nerfs out but the ones with the heel guards will be out any week or day. PRM has Nerfs out now with built in heel guards but to me the PRM's look like fidos a$$. I saw them for sale on Ebay. I own and love the PRM skid plates though! Nice stuff!
Bling Star just started shipping but they have a large list of back orders so if you order from them now, you could be waiting a month or more. I am supposed to get my Bling Star nerfs next week but who knows.. I guess they run them in batches of 20 and my back order is within the next lot of 20 which should be shipping first of the week so I have my finger crossed.
From what I have seen, the IMS-Roll nerfs are some the of nicest nerfs with heel guards that I have seen. While I have not seen them for the LTR, if they look anything like the ones in the ads, they are going to be really nice. I wish I was more patient! I prefer the look of the aluminum heel over the net version that Rath offers, but that is just me.
The AC's with the heel guards look strange with their "bullet hole" perferations. To me they look strange. I like the larger cutouts on the Bling star and IMS heel guards. I think they look less clunky.
