The energized packet of Tibanna must be discrete in of itself because it is quite clear most of them contain no solid projectile.
Allow me to try and summarize both theories as I understand them.
My theory
Tibanna gas is energized and turned into plasma, this is processed through the blasters collimating circuits and the end product is an energy bolt with anti-gravitational(or gravity-ignoring) properties that travel in a tight helix, giving them slower than light forward propagation and no arcing in gravity wells, the bolt's visible glow is a side effect of decaying back into "normal" particles and the forward tip of it might not always be visible, hence why we sometimes see damage before impact with blasters.
The speed of the bolt might be dependant on the power of the shot or it might be set manually(like short range, medium range and long range), or the gun might adjust itself for that automatically(might use an invisible range finding laser to determine the most appropriate bolt speed).
The collimating circuits mentioned in sources might be responsible for bolt speed.
Pg. 7: Common blaster weapons use high-energy gas for ammunition, activated by a power cell and converted into plasma. The plasma is released from a magnetic bottle effect to fire through collimating componets as a coherent energy bolt. Inherent instabilities limit the ability to precisely aim a blaster bolt, but knowing one's weapon well can strengthen marksmanship. Plasma energy is dissipated as the bolt travels, limiting range as the energy as the energy becomes incoherent. Longer range is developed by longer blast tubes, which align the plasma carrier waves more closely through additional galven circuitry, lens crystals, or other collimating devices.
(ref: Star Wars The Visual Dictionary)
Galven circuitry
(or another method of collimating, this collimation method might be the big difference between blasters, laser-cannons and TL's and all their weird behaviour) focuses the blaster bolt which is unstable due to it being some funky exotic energy that likes to travel in a helix rather than straight forward.
The bolt being made of some kind of funky light also makes the presence of crystals e a little more understandable, albeit not alot.
The blob theory is pretty much the same except that the "blob" is energized tibanna gas that has antigravitational properties and is launched through a magentic bottle(magnetic acceleration?).
This blob of non-solid matter is able to keep itself cohesive and contain a large amount of energy without wanting to burst apart, the bolt looses energy through it's glow.
Same reasons for varying bolt speed.
Well I think my theory works better in regard to the directed release of the energy and certain technicalities mentioned in EU sources, the blob theory however is in agreement with various mentions of blasters being some kind of particle weapons, as well as being more in line with the AOTC:VD and it's novelisation.
Though I find the thought of the blob harder to visualize than I do a helix of energy.
