Personally, if you have the skill, I'd break out the fishing rod and catch the Trumpet shells so everything is profit. Lacking that, Guffy tends to use a synth for 1-2 maybe 3 levels where as I know a lot of crafters like to grab a synth 6 levels prior, pop an advanced synth help and pound down on the synth until its exhausted. For Bonecraft (and the other crafts), the higher level synths usually take nonstackable materials, which can be a real pain considering the need to camp the AH or haul around the remaining materials while you farm the nonstackables and craft on the fly. This aside, his guide isn't *bad*, but everyone has their own preferences when it comes to which synths to use for their levels depending on jobs leveled, subcrafts, AH prices on their server, competition for synthing supplies, and, more often than most, NPC value for the completed item.
Dive head first into FFXIAH.com and ffxiclopedia.org, compare prices, costs, NPC availability and competition, you'll find your path, no worries.
