My most recent trip to VI to fish the Stamp was with Murphy's. Our guide Curtis was great and got us onto some fish. The water was clear with a green tint but was quite low due to unusually low precipitation since Christmas. We were fishing from Curtis's jet sled and some of the bouldery sections of the river were quite shallow, with our sled making contact several times both coming down and going up. It's the price you have to pay for fishing that river. We stayed at an AirBnB for quite a reasonable rate and were very close to the orange bridge, making the drive to the upper river a little more than 15 minutes.
Both Curtis and Kevin are solid guides. I've also fished with Nick at West Coast River Charters and he too is very fishy. Both have jet sleds and I don't think that Murphy's has a drift boat but I believe Nick does. Lastly, there are quite a few spots that you can walk into and fish from shore along that stretch of the river. There is a well documented fisherman's trail that is accessible from Beaver Creak Rd. and if your feeling adventurous you can hike into.
