I've found that I need full range of carburation, from completely closed to full open during use. I've been seriously considering an Omni purchase (really TI Woody XLS vs Omni XL), but I can't help but wonder if I'm not going to be happy with a single carb setting.
Im thinking about doing the same, is it worth the price difference?
Well, the Omni XL and Woody XLS measurers in at 109mm and is longer than the 92mm M by 17mm. The extra length is luxurious and can be easier to spin especially for those with largest hands.
The M is the entry level, all stainless steel Vapcap. The Ti tipped Vapcaps (Woodys) have more features and the Omni is the top of the line all titanium Vapcap.
People often suspect that performance must incrementally change from model to model. I don't think choosing one model over another is about performance so much. All Vapcaps are wonderful efficient vaporizers. I think it's more about budget, function and aesthetics. The basic M stainless steel tip and build vs the Ti tip with wonderful midsection possibilities vs a precision milled condenser and mouthpiece.
The M is the least expensive Vapcap at $50. It has a stainless steel construction, including the tip. It is a great vaporizer but is basic in its design and engineering compared to the titanium tipped series of Vapcaps. Although you can switch out the stainless steel stem for other stems or Body/mp combinations, it does not have full modularity. For example, the Omni condenser will not function properly with the M tip. The ss tip is not quite as nimble as the ti tip with fewer air channels. It likely has a greater conduction ratio. The M is a fantastic economical adventure into the land of the Vapcaps. Everyone should have one. Take the M fishing...if you do drop it in the water, you will likely deeply mourn its loss BUT, it won't be the absolute end of the world.
The ti tipped series of Vapcaps offer full modularity. Buying one will take you on a deep dive into accessory bliss. LEGO for stoners. You don't have to buy all the models, but with parts you can have any one at any time. The titanium tip is more finely crafted and precision engineered than the stainless steel M tip. It has an more air channels and they are wider and deeper and has finely milled fins. There is an addition oring to create a tight fit onto the condenser and into the body or stem. I think that the 5th gen ti tips offer a higher convection ratio.
The full modularity of the ti tipped Vapcaps mean that you can switch up bodies and stems, straight or VonGs, mouthpieces and condensers. You can add an Omni condenser and achieve full dialled customized air flow.
The all titanium Omnivap is the top of the line. It is a beast. The build is very tight, beautifully engineered with incredibly tight tolerances and should be considered a work of art. The Omnivap is beautiful. The Omni condenser/mp is not only a precision milled component which offers a set it and forget it airflow, perfect for use with water pieces, but it's robust core offers additional strength to the overall device. You can run over your Omni with your car but the M or Woody may not fare so well.
Cautious folks should start with the M IMO.
Those that love wood might choose a Woody with it choice of wood midsections and wood mouthpiece. It sports full modularity with other bodies, stems and mouthpieces and can accommodate the Omni condenser if you want to upgrade to an Omni in the future. The Woody has a fully manual air port.
Those that want to own a finely crafted piece of art, indestructible precision workmanship, might dive headlong into the Omni with its dialed in set it and forget it airflow.
