Hopefully we've confused the heck out of the OP at this point.
oh yea, absolutely! thanks for all the input. i have the choice of the Dolphin and the Sinclair, both used but at a super price. this is going to be my "entry level" purchase just to see if i am going to pursue this type of shooting. further down the road, one of the tier one bipods may be in the offing. at this point, i am leaning towards the Sinclair Gen III.
