With springs its always a case of the user identifing whats probably best for them personally, this is probably more correct on the 2nd pair.
For example, I think with Jason the 114's are great for him and last him longest when he was sent higher ones he broke them a lot faster, cant remember what happens when he uses ones lower though but I'm sure he will fill you in.
In almost 3 years working for Pro-Jump we don't get to see too many spring breakages but there are a few bockers out there who consitently break the springs repeatedly, people like Kiola, tundarH & Nero instantly spring to mind and the following is just a theory but I think its very much to do with the amount of sheer force they use to activate the springs and the power they put in it, I think sometimes you need to adapt your technique a little to get the best in a similar way to how some people adapt their technique to stop bottoming out their springs.
Looking at your actual weight, you are going 30 kg over and thats if you have 90's (remember 90's could be anything between 90 - 99 so tell us what the number is at the bottom of your spring as well) So perhaps going a little lower may be better for you as the Black springs are stiffer than the green ones use to be and you probably need to push them a lot to get anything out of them.
The above are just suggestions, you should try a few peoples springs out, theres a few different weights n the demo stilts if the EA's have them and you have a whole variety of sizes between the EA's so you should try a few different sizes. If you decide to go for replacement projump springs if you pm me prior to going ahead I'll see if I can sort you out a deal.
