The SR is good for higher rpm use than a HR. HR are good for 6000rpm easy, probably more like 6500
If you're not spending much time above 6000 rpm then this is (for me) reason enough to use a HR.
With the longer duration of the SR you'll more than likely loose low end power and shift the power band to a higher rpm range as compared to a HR with less duration.
If it's the rough idle sound that you like then look into the Thumper cams, might be a good choice....
I'm not saying that SR is a waste of money but I'm convinced it's not the best choice if it's for a street engine that rarely sees 6000rpm. For an engine that can hold up to 7500rpm and is run on the track the solid lifters are a better choice....IMO....
If you simply WANT a SR cam then why not ....
