Vertical feed neck on a Pirahna EVO

[Sockman]

I'm planning on purcahsing a Pirahna Pro-E EVO in the near future. One of the things I'm concerned about a bit is the feed neck. It's too high for my tastes, so I want to find an aftermarket low-rise style of feed. The trouble is, I don't know what kind of threads are used on the mainbody. I'd assume they are Spyder threads, but I'd really like to hear other reports.

Thanks,
Sockman

Threads

Piranhas use Impulse-threaded feed necks.
Lapco makes a nice low-rise that looks good on the
Evo/Pro-e style body.

Not 100% sure about this, but I don't think Spyders have threaded necks on any models.
