The Sahara were the only tobacco cartridges I liked from V2, and I'd stocked up on them. I can't say I'd compare them to RY4. I'd never had an RY4 before, though, either. When I first switched to SI, I tried the tobacco flavor sampler pack. I didn't care for the RY4 at first, and it grew on me. I certainly liked the Desert Joe better than the Sahara. And 555 blew me away, I really liked it. When I switched to SI, all my cartridges from V2 accompanied the batteries I bought for a relative to try. After a few weeks, I went back to the RY4 and liked it better then.
I gave up my V2 batteries (I donated most of them to charity), they were decent batteries, but my best advice is to get a standard starter kit from Smokeless Image and get the Smooth Sampler to give a try. The cost is much less than you are used to and the customer service goes leaps and bounds beyond what the poor souls over on the other side must endure. The flavor is so much more with SI, too. The SI liquids do not need to be steeped, and the flavor stays pretty consistent throughout the bottle.
Go for the Smokeless Image 4th of July sale. It is one of the best deals you can get on some of the best products on the market. Plus, if you do like what you try and you keep coming back, your reward points will build to the point that you won't have to wait for a sale to get a good deal. SI also has a painless, non-affiliate referral program that makes helping someone else switch a very easy thing to do without making the person feel like you're in it for the money and not their health or best interests.
Welcome to Voltville, Dac311. I hope you will enjoy your visit and maybe you'll like what you see and put down some roots in the neighborhood.
I should mention that RY4 and Desert Joe run pretty much neck and neck for my second favorite flavors from SI, 555 is my first choice. RY4 and Desert Joe are not the same flavors, and both are good in their own rights. You won't go wrong. RY4 has a definite caramel/sweet taste, whereas Desert Joe is more the "Turkish" type blend. I think Desert Joe tastes like it has a little grapefruit flavor in it, everyone else tells me I'm crazy and they don't taste any such thing, and we all like it. lol.
