Are straws less than ideal for gas delivery 
Yes. Its a bodge, frankly. Sorry. All things being relative and all, as piggy back systems are a bit of a bodge themselves, as we all have. But straws are a bit Micky, to say the least. There's a risk of air leaks and the straws snapping off. The lpg should be injected as close to the petrol injectors as possible.
Having said that, I've driven a couple of recently fitted Brc systems with straws tapped into the top of the plenum and they drove ok.
Piggy back?
They work, never heard of one snapping off and the injection point is not far from the gas injector, 20mm or so upstream.
Main advantage is it saves removing the inlet manifold.
Precisely. Rather than remove the plenum and then the inlet to be drilled without swarf through the engine. Its a short cut by half arsed lpg fitters. Having said that its only aluminum swarf.
Actually it cannot be drilled in position as you need to remove the plenum to fit the cut injector cables, then you drill out of the plenum rather from the top.
Not the best solution but not a bad solution.
