While trying to decide what lures I should buy, I come across a common frustration. What do the numbers mean on most of these lures? 

 

for example; lucky craft sammy 115 and lucky craft sammy 110?

 

if i'm correct, it has to do with how deep it goes or something with speed at which it sinks or just size? I'm not actually 100% sure.

 

any help would be great along with some suggestions as to what size is a safe bet to get. 

Length of the lure in millimeters.

Oh wow. That changes everything, I appreciate that man! 

So, if I were to get the Lucky Craft Sammy--which size would you most recommend? 

I've never thrown a Sammy but some other factors come into play as well. While the "110" and "115" are the length in mm, obviously the shorter will be a little more difficult to cast (I have found anyway), weights can vary and depth can vary as well (on diving baits). This comes down to the match-the-hatch theory of what size bait they happen to be chasing that particular day.

What about others, say, River2Sea frogs? Bully WA 45, 55, and 65. What are those numbers? Still length? If so, any exceptions?

Yes. R2S uses the same length in milimaters in their part #s

 

25.4mm in an inch so a 100 bait is about 4"

 

110 Sammy is most popular and a great bait.

A Sammy dives to the same depth, irrespective of length. It's a floating top water. Now, I'm not 100% sure here, but the only Sammy 100 I have is wood. The rest are plastic, and they are 85, 95, 115. The larger the bait, the shorter the walk, and slower the retrieve. They all cast well.

The larger the bait, the shorter the walk, and slower the retrieve. They all cast well.

 

Controlled to a large degree by the angler.

 

 

It is important to note that the nomenclature does not include the plastic diving lip length.

Why quote me and reference a a diving bait?

I was multi-tasking... something I don't  do well.

Not quite true, length not always has something to do with girth and lure weight.
