FYI, I just got off the phone with Rajeff Sports. Below are the head weights for the Sniper lines as well as the new Bass/Musky lines.
Sniper
8wt 315gr
9wt 375gr
10 wt 425gr
Their advice when moving from OBS to Sniper was to use the same line wt. eg If using a 9wt OBS, use a 9wt Sniper.
Bass/Musky
6wt 175gr
7wt 200gr
8wt 225gr
9wt 260gr
10wt 305gr
I was also informed that they are working on updating the website. Once done, this type of information will be listed. Hope that helps others with their line selection.
