Pilot Hi-Tec-C 0.25mm Light Blue

So I decided to try out other sizes of the Hi-Tec-C series, besides the 0.4mm.
This one, the 0.25mm pen, is the thinnest version on the Hi-Tec-C series (so far).
First of all, when trying out this pen, I noticed it feels different from the well known 0.4mm pen. It is a bit "scratchy", and not as comfortable to write with. Also, for some reason, the pen that I got, Light Blue, looks like it is a totally different shade when I place it next to the 0.4mm Light Blue. a much lighter color.

In conclusion, It is a bit of a disappointment, I don't think I'll be using this version of the Hi-Tec-C pens much.

This is actually the same shade of blue, Light Blue.

Mechanical Pencil: 0.3mm vs 0.5mm vs 0.7mm

This time I decided to post a comparison that I was looking for and couldn't find, between different sizes of mechanical pencil's lead.
I usually use the 0.5mm, which is the standard pencil around here. After trying out the  0.7mm, it seems to feel too "fat" for me to write with. The 0.3mm though, was a nice surprise. It is very accurate and comfortable to write with - although it is visibly lighter than the 0.5mm lead.

Left to right: 0.3mm,0.5mm and 0.7mm.

This one had strong lighting, so the colors seem a bit light. 

Pilot Hi-Tec-C 0.4mm Sear Blue
This shade is one of my favorite blue shades. It's a bit light, but not too light to read. here is a picture with it next to Blue and Light Blue :

and here is a comparison to other Hi-Tec-C 0.4mm blue shades(and black):

Pilot Hi-Tec-C 0.4mm Lavender
This shade is a bit softer than the regular violet, I actually like it better - and it also works nice with other purples and pinks. Here are some text samples so you can see what I mean.

 

Pilot Hi-Tec-C Blue-Black 0.4mm

This pen writes smoothly, no stutters or dry-ups (I've been using it for about a year)
This color could be an in interesting replacement for black, when black is too "serious".
Here are some pictures, which are the most important part, right?

Piolt Hi-Tec-C Slim Knock 0.4mm Blue and Blue-Black

I ordered these pens from Ebay about 8 months ago, I wanted to try this version of the Hi-Tec-C pens, and found out it's got some advantages and some disadvantages.
to make it simple:

Advantages:
1. Suits right in my notepad.
2. Writes smoothly (just as it should).

Disadvantages:
1. A bit too small, my husband for example did not feel comfortable using it.
2. The ink barrel is significantly smaller than the regular Hi-Tec-C pen.
